How to Install a Gooseneck Trailer Hitch on a 2011 GMC Sierra


Today on our 2011 GMC Sierra 2500, were going to be installing the Curt Gooseneck Hitch, part number C60604. Now, weve already gone ahead and removed the spare tire and exhaust from the vehicle to give us a little more room for working. Our first step will be to cut the heat shield as it will be in the way for our install kit. Ive already marked where were gonna be cutting at these lines here and here. To cut the heat shield, well be using a grinder fitted with a cutting wheel. If you dont have this, a pair of thin snaps and a little patience will suffice.

Now, we have the two crossbars. Notice how the bar here has a cut on it. This will be the bar that goes toward the front. Well next take our rearmost rail and slide it in between the bed of the truck and the frame, across to the other side of the frame. Once in, well turn the rail up vertically with the help of some channel locks, making sure the holes will be at the bottom of the rail.

With that done, well repeat this process for the front rail, also making sure the cut goes over to the gas tank. With our crossbars in place, we can now install our side brackets. This is the side bracket here with the mounting locations for the crossbars on either side. To attach these, well be using the 1/2 x 1-1/2 bolt, a flat washer, and a lock washer. Well put the lock washer on the bolt then the flat washer, and then well loosely install the hardware to hold the bracket into position.

Well repeat this for the other side. With our brackets loosely installed, were ready to mount them to the frame of the truck. Well need to reposition the crossbars. Since it is such a tight fit, you may need to use a rubber mallet to do this. This will align the bracket with the holes existing in the frame.

You wanna get the crossbars as close to the hat channel as possible. To get the hardware needed to these attachment points, well use a fish wire. Well first feed it through the desired location and up this excess hole. Well slide our block on, thread in our bolt and pull them into position. Once there, well remove the fish wire and install our nut. Well repeat this for the other side. With that done, well go ahead and tighten them down. Now, we need to go under the vehicle and install our template for the Gooseneck ball mount. Youll notice the F on the template indicating which way its supposed to be facing, which in the case is towards the front. When installing it, well use the 1/2-inch hardware and tighten it down with our rachet. With that done, you can see this hole in the middle of the template. Well use this as a guide to drill our pilot hole for the Gooseneck ball mount. With our pilot hole drilled, we can now remove the template and drill out our 4-inch hole for the Gooseneck ball mount. With the hole drilled out, well put our bed line back in place to draw out the Gooseneck ball hole in it. Next, well place the provided rubber strip around the cut of the Gooseneck ball. Now, were ready to install the head assembly of the Gooseneck. Its a good idea to get an extra set of hands to help you hold it in place as you put the fasteners in, which will be the bolt lock washer and flat washer. With those installed, well go ahead and tighten them down and then tighten the bolts that connect the crossbars to the brackets. Once tightened, we can torque them down to specification as indicated in the instructions. One of our last steps will be to drill out the holes for the U-bolts. Well be using these holes here as templates for them. Well then install the U-bolts from the top using the flat washer, spring, another washer, and nylon lock nut. Well repeat this for the other three threads. Well then tighten them down until one thread protrudes through the nut. Next, we can install our handle. From the drivers side, well slide in our handle through the slot here. Well then run it through the hole and the head assembly and place it in position with the Gooseneck ball mount area. Now, well place the locking mechanism into position. With that done, well slide the spring onto the handle bar and then place the handle bar into the locking mechanism. Well then place our bolt and nut into position, which will connect the locking mechanism to the handle and tighten it down. Now, well go ahead and test out our Gooseneck assembly, first by placing the handle into the unlock position. Well then place the Gooseneck ball into position and let the handle fall back, which will lock the ball into place. And there you have it for part number C60604 from Curt on our 2011 GMC Sierra 2500.
